Title: Ultrasonic flaw detection tester
Inventor: NISHIU SAKAE
IPC: G01N29/44
Filed: 1985-07-19
Abstract: PURPOSE:To enable automatic recording of distribution state of an abnormal thickness of a structural body to be measured regardless of surface condition, by including a position detector for detecting the position of a probe, a control section, a recording section and the like. CONSTITUTION:A light emitting element 17 such as LED is mounted to a prove 14. An optical semiconductor position detector 18 receives light radiated from the element 17 to detect the position of the probe 14.When the flaw detector 12 is used to carry out a flaw detection for measuring the distribution state of a less thickness part (abnormal thickness) of a structural body 11 to be measured, a worker moved the probe 14 sequentially to several measuring positions within a detection range S of a position detecting sensor of the detector 18. Thus when the detection value of the flaw detector 12 is below a set level range, an X-Y coordinate voltage is fed to a recording section 24 from a control section 15 to indicate the position of the probe 14 at the moment of obtaining the abnormal detection value. This enables automatic recording of the distribution state of the less thickness part thereby elevating the recording accuracy with a shortened working time.
